Abstract

LA INVENCION SE REFIERE A UN DETECTOR DE FASE DIGITAL PARA LA DETERMINACION DE DESPLAZAMIENTOS DE FASE ENTRE UNA COMPARACION DE SEÑAL (VT) DE RELOJ Y UNA SEÑAL (RT) DE RELOJ DE REFERENCIA. LOS MEDIOS (STA, STO) PRIMARIOS GENERAN LAS SEÑALES DE COMIENZO PREPARADAS A PARTIR DE LOS IMPULSOS DE REFERENCIA Y LAS SEÑALES (RT, VT) DE RELOJ DE COMPARACION. UN CONTADOR (ZG, Z) CUENTA LOS IMPULSOS DE UNA SEÑAL (ZT) DE RELOJ DE CONTADOR DE ALTA FRECUENCIA EN LA RANURA DE TIEMPO, ENTRE UNA SEÑAL DE COMIENZO Y LA SEÑAL DE PARADA SUBSECUENTE. EL CONTADO REGISTRADO MEDIANTE EL CONTADOR (ZG, Z) ES UNA MEDIDA DEL DESPLAZAMIENTO DE FASE. LOS DETECTORES DE FASE DIGITALES DE ESTE TIPO EXHIBEN ERRORES DE CUANTIZACION. LA UTILIZACION DE UNA INFORMACION (VZ) DE SIGNO DERIVADA A PARTIR DE LA SEÑAL DE RELOJ DE COMPARACION, QUE GUIA O RETARDA LA SEÑAL DE REFERENCIA, Y LOS MEDIOS (MP) QUE AÑADEN UNA CONSTANTE A LA CUENTA DEL CONTADOR PERMITEN QUE SE REDUZCAN LOS EFECTOS DEL ERROR DE CUANTIZACION DE FORMA SIGNIFICANTE. EL DETECTOR DE FASE PROPUESTO HACE POSIBLE EL DISEÑO DE LAZOS DE CONTROL DE FASE SUMINISTRANDO AJUSTES DE SEÑAL DE RELOJ PRECISAS, DADO QUE SUMINISTRA UNA SEÑAL DE CONTROL INCLUSO CUANDO EL DESPLAZAMIENTO DE FASE ENTRE LAS SEÑALES DE COMPARACION Y LA SEÑAL DE RELOJ DE REFERENCIA ES MUY PEQUEÑO.
